4m-3/4=-9+4m/8 this is my question that i need help with

==============================================

Work Shown:

g(x) = x^2-2

g(-2) = (-2)^2-2

g(-2) = 2

Saying (-2, g(-2)) is the same as saying (-2, 2)

---------------

g(x) = x^2-2

g(1) = 1^2 - 2

g(1) = -1

Saying (1, g(1)) is the same as saying (1, -1)

---------------

Let's find the slope of the line through (-2,2) and (1,-1)

m = (y2 - y1)/(x2 - x1)

m = (-1-2)/(1-(-2))

m = (-1-2)/(1+2)

m = -3/3

m = -1

Now turn to point slope form to find the equation

y - y1 = m(x - x1)

y - 2 = -1(x - (-2))

y - 2 = -(x + 2)

y - 2 = -x - 2

y-2+2 = -x-2+2 ... add 2 to both sides

y = -x

You could use the other point (1,-1) and you'd get the same answer. The slope m = -1 is the same each time.

Answer:

Step-by-step explanation:

Given the expression written by Elizabeth as  3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.

Converting 3.3 and 0.21 to fraction

3.3 = 33/10

0.21 = 21/100

Taking the difference of both fractions

[tex]= \dfrac{33}{10} -\dfrac{21}{100} \\\\= \dfrac{330-21}{100} \\\\= \dfrac{309}{100} \\\\= 3.09\\[/tex]

Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). This large difference makes Elizabeth answer unreasonable.

D.

The estimate would be 30

3​, so her answer is not reasonable

Answer:

[tex] \boxed{ \bold{ \boxed{ \sf{15 \: cookies}}}}[/tex]

Step-by-step explanation:

Total cookies = 150

percentage of cookies that she ate = 10 %

To find : Number of cookies that she ate

[tex] \sf{10\% \: of \: 150}[/tex]

To convert percent into fraction, divide it by 100 and remove the % symbol.

⇒[tex] \sf{ \frac{10}{100} \times 150}[/tex]

⇒[tex] \sf{15 \: cookies}[/tex]

Thus, She ate 15 cookies.

Hope I helped!

Divide by -4:-4x/-4<4/-4

Answer:

  A. 0

  B. -66

  C. 4

  D. 998

  E. -12

Step-by-step explanation:

A. By definition, the sum of anything and its additive inverse is zero.

__

B. If you have trouble with sums, your calculator can help.

  -22 + (-44) = -22 -44 = -66

__

C. -36/x = -9 can be solved by multiplying by x and dividing by -9:

  -36 = -9x

  -36/-9 = x = 4

Since the product of the divisor and quotient is the dividend, dividing the dividend by either gives the other. Here, your dividend is -36 and your quotient is -9. To find the divisor, you can divide -36 by -9, as we did.

__

D. The absolute value function changes the sign of negative numbers to positive:

  |-998| = 998

E. If you have trouble with sums, your calculator can help.

  (−2)−[(−3)−(−7)−(−6)]

  = -2 -(-3 +7 +6) = -2 -10 = -12

Answer:

It will be 1,100,000

Hope it helps!

Answer:

  1,110,000 in standard form

Step-by-step explanation:

To write this number in standard form, put the most significant digit in the number place indicated by the exponent of 10, then put the digits right of it in the corresponding number places to the right of the most significant digit.

__

You will notice that number place values increase the exponent of the base (10) by 1 unit for each place going left. The exponent decreases by 1 unit for each place going right. This is true for a place-value number system in any base.

 Answer:  m=4

Step-by-step explanation:

5(m-2) - 10 = 6 + 2(1 - m)  Apply the distributive property on both sides

5m -10 -10 = 6 + 2-2m         Now combine like terms on both sides

5m -20 = 8- 2m     Now add 2m to both sides

+2m              +2m

7m  - 20= 8    Add 20 to both sides

        +20  +20

7m = 28      Divide both sides by  7

m = 4  

Answer:

x=-5

Step-by-step explanation:

-16=-1+3x

first you add 1 to both sides making it: -15=3x

then you divide both sides by 3

you get -5=x

Answer:

x = -5

Step-by-step explanation:

-1 + 3x = -16

-1 +3x +1 = =16 +1

3x = -15

x = -5

Answer:

x < -3

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

5 - 9(8 - 2x) < 2x - 115

Step 2: Distribute parenthesis

5 - 72 + 18x < 2x - 115

Step 3: Combine like terms

-67 + 18x < 2x - 115

Step 4: Add 67 on both sides

18x < 2x - 48

Step 5: Subtract 2x on both sides

16x < -48

Step 6: Divide both sides by 16

x < -3

And we have our answer!

Answer:

x<-3

Step-by-step explanation:

5−9(8−2x)<2x−115

Use the distributive property to multiply −9 by 8−2x.

5−72+18x<2x−115

Subtract 72 from 5 to get −67.

−67+18x<2x−115

Subtract 2x from both sides.

−67+18x−2x<−115

Combine 18x and −2x to get 16x.

−67+16x<−115

Add 67 to both sides.

16x<−115+67

Add −115 and 67 to get −48.

16x<−48

Divide both sides by 16. Since 16 is >0, the inequality direction remains the same.

x<-48/16

Divide −48 by 16

x<−3

Answer:

5

Step-by-step explanation:

The slope of a line is always rise over run.

We need to make the rise over run equivalent to 2 to find the value of y.

Looking at the x-coordinates, 2 and 6, we can see there is an increase in 4.

Now we ask: What number, times 2, will equal 4?

That is 2.

So we have to make the increase in the y coordinates 2.

If we have the original point 3, an increase in 2 is 5.

So y is 5.

Hope this helped!

Answer:

11 = y

Step-by-step explanation:

Using the slope formula

m = (y2-y1)/(x2-x1)

2 = (y-3)/(6-2)

2 = (y-3)/4

Multiply each side by 4

2*4 = y-3

8 = y-3

Add 3  to each side

8+3 = y-3+3

11 = y

Answer:

m = 3/5

(-50, 50)

Step 2: Find slope m

m = (50 - 80)/(-50 - 0)

m = -30/-50

m = 3/5

Answer:

11325.

Step-by-step explanation:

Step 1: address the formula, input parameters & values.

Input parameters & values:

The number series 1, 2, 3, 4, . . . . , 149, 150.

The first term a = 1

The common difference d = 1

Total number of terms n = 150

Step 2: apply the input parameter values in the formula

Sum = n/2 x (a + Tn)

= 150/2 x (1 + 150)

= 22650/2

1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

Therefore, 11325 is the sum of positive integers up to 150.

The sum of the first 150 odd positive integers is 11325.

The number series 1, 2, 3, 4, . . . . , 149, 150.

The first term a = 1

The common difference d = 1

Total number of terms n = 150

Sum = n/2 x (a + Tn)

= 150/2 x (1 + 150)

= 22650/2

1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

: An integer is positive if it is greater than zero. Example 1, 2, 3 . . . Negative Integers: An integer is negative if it is less than zero. Example -1, -2, -3 . . .

The definition of a positive integer is a whole number greater than zero. The set of positive integers includes all counting numbers (that is, the natural numbers).

Odd numbers are the numbers that cannot be divided by 2 evenly. It cannot be divided into two separate integers evenly. If we divide an odd number by 2, then it will leave a remainder. Examples of odd numbers are 1, 3, 5, 7, etc.

Answer:

[tex]x=-3, y=5, z=6[/tex]

Step-by-step explanation:

1. Divide by 2 both sides in the second equation:

2. From the third equation find z in terms of x:

3. Add up the first and new second equations and find y in terms of x:

4. Put new alternatives instead of y and z in the first equation:

5. Now we can easily find other two unknowns by using their equations by means of x:

Answer:

Step-by-step explanation:

2x + 6y - 2z = 12

12x - 6y + 6z = -30

14x + 4z = -18

6x + z = -12

14x + 4z = -18

-24x - 4z = 48

-10x = 30

x = -3

6(-3) + z = -12

-18 + z = -12

z = 6

-3 + 3y - 6 = 6

-9 + 3y = 6

3y = 15

y = 5

x = -3, y = 5, z = 6

Answer:

[tex]x=13[/tex]

Step-by-step explanation:

So we have:

[tex]\frac{x}{11}=\frac{13}{11}[/tex]

To solve for x, multiply both sides by 11.

[tex](11)\frac{x}{11}=(11)\frac{13}{11}[/tex]

Both the left and the right cancel. Thus:

[tex]x=13[/tex]

Our answer is 13 :)

Answer:

Hey there!

x=13

The denominator is the same for both sides, so to make the equation equal, x has to be 13.
